Eli Whitney (December 8, 1765 – January 8, 1825) was an American inventor best known for inventing the cotton gin (below). This machine, which separates the seed from the cotton, was one of the key inventions of the Industrial Revolution and helped shape the economy of the South by making cotton a profitable crop.
